网站开发毕业答辩ppt软文推广发布

今天是开始学go的第x天，前些日子看了看语言，今天找一个web开发来跟着学，记录一下遇到的问题，方便以后复习查阅。

视频看的是https://www.bilibili.com/video/BV1gJ411p7xC?p=3&vd_source=ab5bdbd04f4142027c66d604d5285204

 视频中用的是goland，我用的vs

如何在vs中建一个项目：

这也是为了解决一个报错：

go.mod file not found in current directory or any parent directory.'go get' is no longer supported outside a module.To build and install a command, use 'go install' with a version,like 'go install example.com/cmd@latest'For more information, see https://golang.org/doc/go-get-install-deprecationor run 'go help get' or 'go help install'.

因为下载gin的时候会报错,就是这个命令：go get -u github.com/gin-gonic/gin

初次尝试go写一个网页还是挺有意思的

package mainimport ("fmt""net/http"
)func sayHello(w http.ResponseWriter, r *http.Request) {_, _ = fmt.Fprintln(w, "Hello jzy")
}func main() {http.HandleFunc("/hello", sayHello)err := http.ListenAndServe(":9090", nil)if err != nil {fmt.Printf("http server failed, err:%v\n", err)return}
}
